Application of Conductive Concrete as a Microbial Fuel Cell to Control H2S Emission for Mitigating Sewer Corrosion

Localized biogenic corrosion and extrication of annoying odors caused by hydrogen sulfide (H2S) have long been a big problem in the management urban sewer systems. H2S emission control sewers via chemically or biologically normal oxidation processes has also investigated extensively is costly. The objective this work was to develop new technology mitigate concentration pipes using conductive concrete. Experimental results after 66 days show that significantly decreased when concrete used as microbial fuel cell. Both ordinary Portland cement were utilized for target experiment. Elemental sulfur observed coating sludge concrete, whereas trend not cement. These observations demonstrate provides an electron pathway from deposited bottom oxygen dissolved surface water electrons generated anaerobic environment Finally, regarding mechanism responsible oxidation, chemical dominant process, biological did play significant role.
